摘要：文章对甲苯甲醇烷基化制备对二甲苯技术进行了分析和讨论，分析了甲苯转化率对产品收率、运行能耗及投资的影响，分析
了甲醇转化率对污水排放系统的影响。经过分析得出，甲苯甲醇烷基化技术制备对二甲苯，产品的选择性很高，非常适于生产对二
甲苯。甲苯甲醇烷基化反应产物中剧毒物质苯的含量非常少，在环境保护方面优于其他芳烃生产工艺。

Abstract: The process using alkylation of toluene and methanol to produce paraxylene is analyzed. The influence of toluene’s conversion
on product yields, unit energy consumption and investment are also analyzed. Otherwise, the conversion of methanol also influences
the downstream waste water processing system. Alkylation technology of toluene with methano is especially suitable for paraxylene
production due to the high selectivity of paraxylene in the product yields. In the product, the amount of toxic benzene is approaching to
zero, so it is more environment-friendly than other technologies.
